C++ Program to Multiply Two Matrices
#include<iostream>
using namespace std;
int main()
{
int
a[3][3], b[3][3], c[3][3], sum=0, i, j, k;
cout<<"Enter
elements of matrix 1 : ";
for(i=0;
i<3; i++)
{
for(j=0;
j<3; j++)
{
cin>>a[i][j];
}
}
cout<<"Enter
elements of matrix 2 : ";
for(i=0;
i<3; i++)
{
for(j=0;
j<3; j++)
{
cin>>b[i][j];
}
}
for(i=0;
i<3; i++)
{
for(j=0;
j<3; j++)
{
sum=0;
for(k=0; k<3; k++)
{
sum = sum + a[i][k] * b[k][j];
}
c[i][j] = sum;
}
}
cout<<"\nMultiplication
of two Matrices is \n";
for(i=0;
i<3; i++)
{
for(j=0;
j<3; j++)
{
cout<<c[i][j]<<"\t";
}
cout<<"\n";
}
return
0;
}
OUTPUT:
Enter elements of matrix 1 : 1
